Technical Note: Database Architecture

This plugin integrates webcalendar-core, a framework-agnostic Composer library that provides all calendar business logic (events, recurrence, iCal, permissions) through 17 repository classes. These repositories require PDO and use exclusively parameterized prepared statements — no raw SQL concatenation. WordPress-specific data (users, options, capabilities) is accessed via $wpdb through the plugin’s Bridge layer (WpUserRepository, WpConfigRepository, etc.). See src/Bridge/PdoFactory.php for the connection factory.

External Services

This plugin connects to the following third-party services:

Nager.Date API

Used for importing public holidays via WebCalendar > Holidays.
* Endpoint: https://date.nager.at/api/v3/

Remote Calendar Sync (User-Configured)

When remote iCal subscriptions are configured, the plugin fetches .ics data from
those URLs via HTTP GET. No user data is transmitted to these services.

OpenStreetMap / Nominatim

When a single event page has a location and the map provider is set to OpenStreetMap
(the default), the plugin geocodes the address via the Nominatim API and displays a
map using OpenStreetMap tile servers. The event location string is sent as a search
query. No user personal data is transmitted.

* Tile server: https://tile.openstreetmap.org/
* OpenStreetMap Terms of Use
* Nominatim Usage Policy
* OpenStreetMap Privacy Policy

Google Maps Embed API

When the map provider is set to Google Maps in settings, single event pages display
an embedded Google Map for the event location. The event location string and your
Google Maps API key are sent to Google. No other user data is transmitted.
* Endpoint: https://www.google.com/maps/embed/v1/place
* Google Maps Platform Terms of Service
* Google Privacy Policy

Add to Calendar Links

Single event pages include “Add to Calendar” buttons that generate links to Google
Calendar, Outlook.com, and Yahoo Calendar. When a visitor clicks a button, the event
title, date, time, location, and description are passed as URL parameters to the
chosen service. No data is sent until the visitor clicks.

Development & Source Code

Full unminified source for this plugin is included in this distribution under GPL-2.0-or-later — you do not need to download anything external to rebuild the compiled assets.

What ships in this zip:

src/ — unminified React/JSX source for all admin components, frontend calendar, and the mini-calendar widget
build/ — the pre-compiled minified bundles (what the plugin actually loads at runtime)
package.json + package-lock.json — Node build manifest and lockfile for reproducible npm install
composer.json — PHP dependency manifest

Rebuilding the compiled assets from source:

Prerequisites: PHP 8.2 or higher with Composer 2, Node.js 20 or higher with npm 10.

composer install — install PHP dependencies
npm install — install JavaScript build dependencies (@wordpress/scripts, React, Toast UI Calendar, Leaflet, Tiptap)
npm run build — compile src/index.js and src/frontend.js into the minified bundles under build/

The compiled output in build/ is byte-reproducible from the matching src/ at the same version using this toolchain.
